Application filed May 27, 1926, Serial No. 112,134, and in Germany December 23, 1925.

In matrix setting and type line-casting machines of the kind m which the matrlx bars are moved on endless guiding wires,

feeding members move the cast matrix bars on the wires towards the magazine'along an orbital path and immediately return to their initial position to collect and feed a further setof matrix bars cast in the meantime. The, constructional difficulties involved in moving the feedin members correc'tly are not easily overcome, as the matrix bars must be moved substantially along a semi-circle and simultaneously raised, so that they may r ach the magazine. A comparativeiy large amount of friction and therefore of wear is produced on the suspension e es of the matrices because they rise on the wires while carrying out their semi-circular movement.

According to the present invention this disadvantage is overcome by substituting the semi-circular portion of the guiding means which collects the matrices moved out of the casting point by a separate frame supported on oscillating means and rotatable about a vertical axis.

For the purpose of explaining the invention an example embodying the same has been shown in the accompanying drawings, in which the same reference characters have been used in all the views to indicate corre- In said drawings,

Figure 1 is a side elevation of the oscillating arms in their lowermost position;

Figure 2 shows the said arms in their uppermost position;

Figure 3 is an end elevation of Figure 1;

Figures 4 and 5 are details, and

Figure 6 is a diagrammatic plan of the matrix-guiding means. i

A rod 9 is vertically reciprocated by the mechanism of the machine through the medium of a link 9 and of a bell-crank lever 1' (Figures' 1 and 2). The end of the arms 6 mounted as double-armed levers on horizontal pivots d on the frame 0 of the machine are pivotally attached to the said rod 9. A spindle h is rigidly mounted on the said arms and is provided with a bevel wheel 2'. A frame 0 is articulated to the arms 0 below the said spindle. A second frame Z carrying guiding wires Z) (Figure 5) is mounted in the frame 0 on pivots m and is rotatable about its vertical central axis. A small bevel wheel is mounted on the upper pivot 77?. and is adapted to mesh with-the bevel wheel 71. hen the arms eoscillate upwardly from the lowermost position shown in Figure 1 into the position shown in Figure 2 the bevel wheel 2' is moved through a similar angle, so that the bevel wheel Z: is rotated through 180 with its frame Z (Figure 4:). Thereby the matrix bars hanging on the wires 5 are likewise rotated through 180.

The device works as follows:

The matrix bars 79 used at the casting point a. (Figure 6) are transferred in the usual way to wires 6 and thereby into the frame Z carried by the frame 0. The mechanism of the machine nowcausesthe arms-e to oscillate upwardly about the pins d, the frame Z being simultaneously rotated tnrough 180 about its pivots we so that the wires and matrices which in Figure 1 are on the right of the frame c, are now on the left thereof when the various elements are in the position shown in Figure 2 (see also Figure 6). The matrices are therefore turned through 180 as if they had moved along a semi-circle, and may now be transferred to the wires f leading to the magazine. The arms 6 and the frames 0 and Z are then returned to their initial position to collect new matrix bars coming from the casingpoint a.

The frame 0 is provided with projections a striking against the stationary frame 0 of the machine, when the arms 6 are in the upper or lower end-positions, thereby securing the exact positions of the wires 12 to the wires a or f.

I claim:

1. In a type line setting and casting machine, matrices guided on wires, a frame disposed intermediately the wires leading from the casting place to the magazine and carrying corresponding guiding wires, means to swing said frame up and down and means to rotate the frame about a vertical axis.

2. In a type line setting and casting machine, matrices guided on wires, a frame disposed intermediately the wires leading from the casting place to the magazine and carrying corresponding guiding wires, oscillating arms carrying said frame and swinging the same from the casting place upwards to the guiding wires leading to the magazine and back and means to rotate the frame about a vertical axis.

3. In a type line setting and casting machine, matrices guided on Wires, a frame disposed intermediately the Wires leading from the casting place to the magazine, a second frame disposed rotatably in the first frame, guiding Wires in said second frame, oscillating arms pivotally carrying the first frame, means to oscillate said arms around an arcuate path and means to rotate the second frame.
